Synthetic resin yog cov khoom siv polymer, uas yog tsim los ntawm kev sib txuas cov khoom siv tsis tshua muaj molecular - monomers (xws li ethylene, propylene, vinyl chloride, thiab lwm yam) rau hauv macromolecules los ntawm polymerization.Cov txheej txheem polymerization feem ntau siv hauv kev lag luam muaj xws li bulk polymerization, suspension polymerization, emulsion polymerization, kua polymerization, slurry polymerization, roj theem polymerization, thiab lwm yam. Cov khoom siv raw rau kev tsim cov khoom hluavtaws muaj ntau.Thaum ntxov, lawv feem ntau yog cov khoom siv roj av thiab calcium carbide calcium carbide.Tam sim no lawv feem ntau yog cov roj thiab cov khoom siv roj, xws li ethylene, propylene, benzene, formaldehyde thiab urea.

Bulk polymerization yog txheej txheem polymerization nyob rau hauv uas monomers yog polymerized nyob rau hauv qhov kev txiav txim ntawm pib los yog kub, lub teeb, thiab hluav taws xob tsis ntxiv lwm yam xov xwm.Cov yam ntxwv yog tias cov khoom yog ntshiab, tsis muaj kev sib cais thiab purification yog qhov nyuaj, kev ua haujlwm yog qhov yooj yim, thiab kev siv tus nqi ntawm cov khoom siv ntau lawm.Nws tuaj yeem ncaj qha tsim cov khoom zoo xws li cov kav dej thiab cov phaj, yog li nws tseem hu ua block polymerization.Qhov tsis zoo yog tias cov viscosity ntawm cov khoom nce ntxiv nrog rau kev nce qib ntawm cov tshuaj tiv thaiv polymerization, kev sib xyaw thiab kev hloov hluav taws xob yog qhov nyuaj, thiab qhov kub ntawm lub reactor tsis yooj yim los tswj.Cov txheej txheem polymerization feem ntau yog siv los tsim cov resins xws li polyadditional methyl acrylate (feem ntau hu ua plexiglass), polystyrene, low-density polyethylene, polypropylene, polyester thiab polyamide.
ncua kev kawm ntawv polymerization
Suspension polymerization yog hais txog cov txheej txheem polymerization nyob rau hauv uas cov monomer dispersed mus rau hauv cov tee dej nyob rau hauv qhov kev txiav txim ntawm mechanical stirring los yog vibration thiab dispersant, thiab feem ntau yog raug tshem tawm hauv dej, yog li nws tseem hu ua hlaws polymerization.Cov yam ntxwv yog: muaj cov dej ntau hauv lub reactor, viscosity ntawm cov khoom yog tsawg, thiab nws yog ib qho yooj yim rau hloov tshav kub thiab tswj;Tom qab polymerization, nws tsuas yog yuav tsum tau mus los ntawm kev sib cais yooj yim, ntxuav, ziab thiab lwm yam txheej txheem kom tau txais cov khoom siv cob, uas tuaj yeem siv ncaj qha rau kev ua molding;cov khoom yog tus ntshiab, tusyees.Qhov tsis zoo yog qhov muaj peev xwm ntawm cov reactor thiab purity ntawm cov khoom tsis zoo li cov txheej txheem polymerization ntau, thiab txoj kev nruam tsis tuaj yeem siv rau kev tsim khoom.Suspension polymerization yog dav siv hauv kev lag luam.
